1.Types a me nā hiʻohiʻona hana o ka generator
ʻO ka generator he mea hana e hoʻoulu ai i ka uila ke hoʻokau ʻia i ka mana mechanical.Ma kēia kaʻina hoʻololi, hiki mai ka mana mechanical mai nā ʻano ʻano like ʻole o ka ikehu, e like me ka ikehu makani, ka ikehu wai, ka ikehu wela, ka ikehu lā a pēlā aku.Wahi a nā ʻano uila like ʻole, hoʻokaʻawale ʻia nā mea hana i nā mea hana DC a me nā mea hana AC.
1. Nā hiʻohiʻona hana o DC generator
Loaʻa i ka generator DC nā hiʻohiʻona o ka hoʻohana maʻalahi a me ka hana hilinaʻi.Hiki iā ia ke hāʻawi pololei i ka ikehu uila no nā ʻano mea uila āpau e koi ana i ka mana DC.Eia nō naʻe, aia kahi commutator i loko o ka DC generator, kahi maʻalahi e hana i ka uila uila a me ka haʻahaʻa haʻahaʻa.Hiki ke hoʻohana pinepine ʻia ka mea hana DC e like me ka mana DC no ka kaʻa DC, electrolysis, electroplating, charging and excitation of alternator.
2. Nā hiʻohiʻona hana o ka alternator
ʻO ka mea hana AC e pili ana i ka mea hana e hoʻohua ai i ka AC ma lalo o ka hana o ka ikaika mechanical waho.Hiki ke hoʻokaʻawale ʻia kēia ʻano generator i ka hana mana AC synchronous
ʻO ka mea hoʻoheheʻe synchronous ka mea maʻamau i waena o nā mea hana AC.Hoʻoulu ʻia kēia ʻano mīkini hana e ka manawa DC, hiki ke hāʻawi i ka mana hana a me ka mana reactive.Hiki ke hoʻohana ʻia e hāʻawi i ka mana i nā lako ukana like ʻole e koi ana i ka mana AC.Eia kekahi, e like me nā ʻano mea hoʻohana like ʻole i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia nā mea hana synchronous i nā mea hoʻoheheʻe turbine mahu, nā mea hana wai, nā mea hana diesel a me nā turbine makani.
Hoʻohana nui ʻia nā mea hoʻololi, no ka laʻana, hoʻohana ʻia nā mea hana no ka lako mana i nā kikowaena mana like ʻole, nā ʻoihana, nā hale kūʻai, ka lako mana standby home, nā kaʻa, etc.
Nā hiʻohiʻona a me nā ʻenehana o ka mīkini hana
I mea e hoʻomaʻamaʻa ai i ka hoʻokele hana a me ka hoʻohana ʻana i ka mīkini hana, ua hoʻohui ka mokuʻāina i ke ʻano o ka hui ʻana o ke kumu hoʻohālike generator, a hoʻopili i ka papa inoa generator ma ke kūlana maopopo o kona pūpū, ʻo ia hoʻi ka mea nui i ke ʻano generator, ka helu helu, ka mana helu. ka lako, ka mana helu, ka papa insulation, ka alapine, ka mana a me ka wikiwiki.
Ke kumu hoʻohālike a me ke ʻano o ka generator
ʻO ke kumu hoʻohālike o ka mīkini hana maʻamau ka wehewehe ʻana i ke kumu hoʻohālike o ka ʻāpana, me ke ʻano o ka hoʻopuka uila e ka generator, ke ʻano o ka ʻāpana generator, nā hiʻohiʻona mana, ka helu serial design a me nā hiʻohiʻona kaiapuni.
Eia kekahi, he intuitive a maʻalahi nā hiʻohiʻona o kekahi mau mea hana, ʻoi aku ka maʻalahi o ka ʻike ʻana, e like me ka mea i hōʻike ʻia ma ka Figure 6, me ka helu huahana, ka helu helu a me ka helu o kēia manawa.
(1) Volta koho
E pili ana ka volt i helu ʻia i ka hoʻopuka ʻana o ka volta helu e ka mea hana ma ka hana maʻamau, a ʻo kV ka ʻāpana.
(2) Ua helu ʻia i kēia manawa
Kuhi ʻia kēia manawa i ke au hana kiʻekiʻe loa o ka mīkini hana ma lalo o ka hana maʻamau a hoʻomau, ma Ka.Ke helu ʻia nā ʻāpana ʻē aʻe o ka mīkini hana, hana ka mea hana i kēia manawa, a ʻaʻole e ʻoi aku ka piʻi ʻana o ka wela o kāna wili stator ma mua o ka pae i ʻae ʻia.
(3) Ka māmā holo
ʻO ka wikiwiki o ka mea hana e pili ana i ka wikiwiki o ka hoʻololi ʻana o ka pahu nui o ka mea hana i loko o 1min.ʻO kēia ʻāpana kekahi o nā ʻāpana koʻikoʻi e hoʻoholo ai i ka hana o ka generator.
(4) Ka pinepine
ʻO ka pinepine e pili ana i ka pānaʻi o ka manawa o ka hawewe sine AC i loko o ka mea hana, a ʻo kāna ʻāpana ʻo Hertz (Hz).No ka laʻana, inā ʻo 50Hz ka alapine o ka mea hoʻomohala, hōʻike ia i ka hoʻololi ʻana o ke kuhikuhi o kāna ʻano ʻokoʻa a me nā ʻāpana ʻē aʻe he 50 mau manawa.
(5) He kumu mana
Hoʻopuka ka mea hana i ka uila ma ka hoʻololi electromagnetic, a hiki ke hoʻokaʻawale ʻia kona mana hoʻopuka i ʻelua mau ʻano: mana reactive a me ka mana hana.Hoʻohana nui ʻia ka mana reactive e hoʻoulu i ka māla magnetic a hoʻololi i ka uila a me ka magnetism;Hāʻawi ʻia ka mana hana no nā mea hoʻohana.I ka huina o ka mana o ka generator, ʻo ka hapa o ka mana ikaika ka mea mana.
(6) Hoʻohui stator
Hiki ke hoʻokaʻawale ʻia ka pilina stator o ka generator i ʻelua ʻano, ʻo ia hoʻi ka pilina triangular (△) a me ka pilina hōkū (ke ʻano Y), e like me ka mea i hōʻike ʻia ma ke Kiʻi 9. I loko o ka generator, ua hoʻopili pinepine ʻia nā wili ʻekolu o ka stator generator i kahi. hoku.
(7) Papa insulation
ʻO ka papa insulation o ka mīkini hana e pili ana i ka pae kiʻekiʻe o ke kūpaʻa wela o kāna mea insulation.I loko o ka generator, ʻo ka mea insulating kahi loulou nāwaliwali.He mea maʻalahi ka mea e hoʻolalelale i ka ʻelemakule a hiki i ka pōʻino i ka wela kiʻekiʻe loa, no laila ʻokoʻa ka pae pale wela o nā mea insulating like ʻole.Hōʻike pinepine ʻia kēia ʻāpana e nā leka, kahi e hōʻike ai ʻo y he 90 ℃ ka wela wela, a he 105 ℃ ka wela wela, e hōʻike ana he 120 ℃ ka wela wela, B hōʻike i ka wela. -ʻo ka mahana wela he 130 ℃, hōʻike ka f he 155 ℃ ka mahana wela, hōʻike ka H he 180 ℃ ka mahana wela, a ʻo ka C ke hōʻike nei ʻoi aku ka mahana wela ma mua o 180 ℃.
(8) 'ē aʻe
I loko o ka mīkini hana, ma kahi o nā ʻenehana loea i luna, aia kekahi mau ʻāpana e like me ka helu o nā pae o ka mea hana, ka nui o ke kaumaha o ka ʻāpana a me ka lā hana.He intuitive a maʻalahi kēia mau ʻāpana i ka heluhelu ʻana, a no nā mea hoʻohana ke nānā aku i ka wā e hoʻohana ai a kūʻai ai.
3、 Hōʻailona hōʻailona o ka mea hana ma ka laina
ʻO Generator kekahi o nā mea koʻikoʻi i nā kaapuni mana e like me ka uila uila a me ka mea hana mīkini.Ke kahakiʻi ʻana i ke kiʻikuhi e pili ana i kēlā me kēia kaapuni mana, ʻaʻole ʻike ʻia ka mīkini hana e kona ʻano maoli, akā kaha ʻia e nā kiʻi a i ʻole nā kiʻi, nā leka a me nā hōʻailona ʻē aʻe e hōʻike ana i kāna hana.
